General Description

Electronic cruise control is a speed control system. The system maintains a desired vehicle speed under normal driving conditions. However, steep grades may cause variation in the selected speeds. The electronic cruise control system has the capability to perform the following functions:
^ Cruise
^ Coast
^ Resume speed
^ Accelerate
^ "Tap-up"
^ "Tap-down"

The cruise control system includes the following main components:
^ The functional control switches
^ The cruise control module assembly
^ A vehicle speed sensor
^ The cruise control release switch assembly
^ The stoplamp switch assembly

The cruise control system uses a cruise control module assembly in order to obtain the desired vehicle cruise operation. The following 2 components in the module are primarily responsible for this operation:
^ An electronic controller
^ An electric stepper motor

The electronic controller monitors the vehicle speed. The controller operates the electric stepper motor. The motor moves a band and throttle linkage in response to the controller in order to maintain the desired cruise speed. A low speed limit feature in the cruise control module assembly prevents system engagement below a minimum of 40 km/h (25 mph). Functional switches on the multi-function turn signal lever operate the controller.
